Yours is a difficult case to know how to respond to effectively.

I can only suggest some reading material that has been helpful:

"Forgiving and Moving On"
"Keep It Simple"
"Days of Healing, Days of Joy"
The Big Book "Alcoholics Anonymous"

I have read that the medication Naltrexone is effective in stopping cravings for alcohol.
You might ask your personal physician about that. (Doctors are bound by law, I think,
to have matters kept private in most states.)

There are probably others here who could talk to you about your situation and give
you more helpful advice. These are the sources that I use for meditation, and they
can be very uplifting and revealing for insights into how families work and responsibilities
of individuals in finally finding freedom. It is a kind of bondage, isn't it?

About bipolar illness --which may be one reason why you "self'-medicate" with alcohol; that
needs to be treated by a psychiatrist in order to bring that illness under control. It can get
worse over the long run without treatment.
